Vehicle ran fine, had rough cold start and then would clear out after 10 to 15 seconds. Kept getting P0170 code, cleared it with OB11 device and would come back soon after. Read about disconnecting the battery for 30 minutes. Disconnected battery, now no codes stored or other codes but now runs like crap, no power and will not go over 4200 RPM and starts to misfire. Read about the MAF sensor and cleaned it with the recommended cleaner.
